Abstract (en)
[origin: EP0184457A1] A rotor-shaft assembly for a turbocharger includes a ceramic solid hubbed turbine rotor (32) having an integral stub shaft (70) interference fit within one end of a generally cylindrically shaped sleeve member (72). The sleeve member (72) has a hub portion (80, 82) adapted to mate with a piston ring seal (60) and a coaxial bore therethrough. The interference fit, which is defined by a change in the diameter of the bore, gradually reduces the compressive forces acting on the stub shaft (70). A metal shaft (36) is brazed within the other end of the sleeve member (72) in a torque transmitting relationship.
